In the equipment or liquid need to be heated, you need to choose a different heating device that is the heating tube. The use of different environments requires different heating tubes to work. There are different environments for dry heating and heating in liquids. In industrial equipment, dry heating tubes are mostly stainless steel heating tubes, fin heating tubes, and no heat sinks. Their common feature is the use of copper plating on the surface of the material or stainless steel, the main role is to heat the air. In life, we will also see the use of carbon steel heating pipe, but after many studies and practical findings have certain drawbacks, carbon steel material is not easy to rust in the often working environment, otherwise it will not be a period of time Easy to oxidize. Therefore, the selected material is basically stainless steel.
The heating tube is dry tolerant, but the dry heating tube and the liquid heating tube are essentially different. Heating in the liquid heating tube requires accurate knowledge of the environment in which the liquid heating tube is located, whether it is water or corroded. Sex liquid. If the water is heated, the surface of the same material as stainless steel can be used for heating. If the liquid is corrosive, a stainless steel heating tube 316, a Teflon heating tube, a titanium tube, etc. can be selected depending on the size of the corrosion. If it is a heating oil, you can use carbon steel or stainless steel material, carbon steel material cost is lower, used in the heating oil does not rust. From the aspect of power, it is generally recommended that when heating water and other media, the power per meter should not exceed 4KW, and when heating oil, it should not exceed 2.5KW per meter.
Because of the difference in the environmental choices between dry-fired heating pipes and liquid heating pipes, their use will vary according to the choice of the environment. For example, a dry-fired heating tube, a single-headed tube with a heated abrasive, a finned tube for heating air, and a stainless steel tube for the oven are designed according to the customer's requirements for different shapes and power. In general, the power of a dry-fired pipe is set to no more than 1 kW per meter, and in the case of fan circulation, it can be increased to 1.5 kW. From the aspect of considering the life of the dry burning tube, it is better to have temperature control and control within a tube's acceptable range. This will not allow the tube to be heated all the time and exceed the temperature to which the tube can withstand, no matter what the quality of stainless steel is. Heater will also be bad.
The liquid heating tube structure is respectively round, square and bolt-shaped, and the square, bolt-shaped structure is compact, occupying space is small, and it is easy to arrange and arrange. The liquid heating tube must be completely immersed in water during use to avoid empty burning. The scale on the surface of the tube needs to be regularly removed so as not to affect the heat dissipation and shorten the service life. Users can use according to different requirements options.
